.Application filed September l2, 1906. Serial No. 334,302.

To all whom it Muay concern:

Be it known that I, HORACE FALK NEU- MEYER, a citizen of the United States, residing at Macungie, in the county of Lehigh and State of Pennsylvania, have invented a new and useful Flash-Light Lamp, of which the following is a specification.

My invention relates to an improved flashlight apparatus, and has for one of its objects to provide an apparatus of this character which is simple and durable in construction, easy of operation and free from danger.

A further object of the invention is to provide an apparatus adapted for use in flashlight photography and capable of producing from magnesium or other suitable material, one or more flashes of light, of short or long duration, dependent upon the will of the operator.

A still further object of the invention is to provide an apparatus having separable parts, so that, when desired to carry the same in a valise, pocket or the like, it can be packed in a compact form; and also means for preventing the egress of the magnesium from the magazine when the apparatus is thus packed.

In the drawings Figure 1 is a top plan view of the complete apparatus. Fig. 2 is a vertical sectional view, taken on the line 2 2 of Fig. 1, and showing the apparatus ready for operation. Fig. 3 is a vertical sectional view of the magazine, showing the caps thereof in position for preventing the egress of its contents. Fig. 4 is a front elevation of the upper cap showingthe arcuate slot. Fig. 5 is an end view of the cylinder taken on the line 5-'5 of Fig. 3. Fig. 6 is a front elevation of the upper cap showing a modified form of the discharge openings.

The same parts of the invention as shown in the drawings are designated by similar reference numerals.

Referring to the drawings, 1 designates a preferably metallic open-ended cylinder which constitutes a receptacle or magazine for powdered magnesium or other suitable inflammable material. Located in the lower end of the magazine is an air-tube 2, having one end 3 of its horizontal portion 4 fitted upon a stud 5 extending inwardly from the wall of the magazine. The other end of the horizontal portion extends through the wall of the magazine at a point directly opposite the stud 5 and terminates in a nipple 6 for the attachment of a flexible air-tube 7 through which'air under pressure is led to the air tube 2. The air-tube 2 also comprises a vertical portion 8 having threaded connection at its upper end 9 with the horizontal portion 4 of said tube. This vertical portion 8 of the air-tube is coaxial with the magazine and the lower or discharge end 10 is extended beyond the lower end 11 of the cylinder.

The lower end of the cylinder is closed by a screw-cap 12, preferably having an integral external knob 13 to facilitate the adjustment thereof.l The upper or inner surface of the cap 12 is provided with an axial concavity or depression 14 adapted to receive the discharge end of the air-tube in one position of the cap.

The upper end of the cylinder is closed by a second screw-cap 15 having an arcuate opening 16 located near the top of its annular wall; the walls of the opening being upwardly inclined in a manner to cause the powder to be projected in an upward direction. lf desired, a series of openings 16"1L may be substituted for the arcuate opening or slot 16, as shown in Fig. 6 of the drawings.

Each of the caps 12 and 15 is provided with a knurled edge 17 to facilitate the turning of the cups and their consequent adjustment longitudinal of the cylinder.

Integral with the cylinder is a socketed projection 18 located on the opposite side of the cylinder to the nipple 6 and at the other end of said cylinder. Extended into the socketed projection 18 is a stud 19 rigidly secured to, by means of the rivets 26, and supporting `a pan 20. This pan is constructed of any suitable material and may be of any desired shape. Within the pan and secured to the bottom 21 thereof by means of rivets or other-suitable devices 2-2, is an absorbent pad 23, preferably asbestos or other noncombustible material. The upwardly and outwardly inclined sides 24 of the pan 20 are rigidly sustained in position by means of the reinforcing wire 25.

The operation of the apparatus is as follows: After assembling the various parts of the apparatus, and filling the magazine with owdered magnesium or other inflammable material, the lower screw-cap 12 of the magazine is adjusted to insure an air-gap between the discharge end 10 of the vertical portion of the air-tube 2, and the axial concavity or depression 14 located in the upper or inner surface of the cap. The second or`upper screw-cap 15 of the magazine is adjusted to a position that will uncover the passage 16,

IOO

IIO

pressure is then applied to the free end of the l '.[iexible' tube 7. The air is then forced. through the flexible tube 7 and the air-tube 2. Afterpassing from the discharge end 10 l of the vertical portion S of the air tube 2, the

air strikes the concavity or depression 14 and rebounds therefrom in a uniform manner throughout the magazine, thus 'forcing the contents therein through the arcuate opening 16 in an upward direction over the pan 21. The inflammable liquid in the pan 21 being inflamed, the powdered magnesium explodes as it comes in contact with said iame, and a flash oi' light is thereby produced. The density and length of this iiash is dependent upon the amount and pressure of air sent into the magazine When desired to carry the apparatus in a valise, pocket or the like, the flexible tube 7 and the pan 21 are disengaged from the magazine. The two screw-caps 12 and 15 are tightly screwed on their respective ends of the cylinder. In this position, the wall of the upper cap 15 closes the arcuate slot 16, and the concavity or depression 14 oi' the lower ca 12 closes the discharge end 16 oi the vertical portion 8 of the air-tube 2. lt will, therefore, be seen that the ingress of air and the egress of the magnesium or other contents of the magazine, will be prevented.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent is:-
